New Delhi, Scientists have created a simple, cost-effective, biocompatible, transparent nanogenerator that can generate electricity from all-around vibrations for use in optoelectronics, self-propelled devices and other biomedical applications.
This fabricated device can light up to 11 LEDs simultaneously when tapped gently with the hand.
Due to the increasing threat of global warming and the energy crisis, the search for renewable energy sources with low carbon emissions continues.
Resources associated with renewable energy are the solution to these problems.
Some non-traditional methods of generating electricity include piezoelectric, thermoelectric, and electrostatic techniques used in devices such as touch screens, electronic displays, etc.

Triboelectric Nano Generators (TENGs) use mechanical energy in the form of vibrations found everywhere in various forms to generate electricity.
Energy-harvesting TENG works on the principle of the creation of electrostatic charge through the instantaneous physical interaction of two dissimilar materials.
This mechanism moves electrons back and forth between a membrane or film made up of Tribo layers.
The methods used to design TENGs were costly, such as photolithography, and additional processes such as electrode preparation were used.
Dr. Sankara Rao of the Center for Nano and Soft Matter Sciences, Bangalore, an autonomous institute under the Department of Science and Technology, Government of India, and his team have designed a transparent TENG using Thermoplastic Polyurethanes.
Doctor's blade technology has been used to design it. The device made by this technology is very efficient, robust, and provides reproducible output for a long period of operation.
Its results were published in the 'Journal of Nanoscience and Nanotechnology.
